What are some real-world examples of encapsulation?

Encapsulation is a fundamental concept in object-oriented programming. A real-world example is a car. The car's internal mechanisms are hidden from the driver, who interacts with the car through a user interface like the steering wheel and pedals.

Can you give me another example?

Sure! Think of a bank account. The details of the account, like the balance and transaction history, are encapsulated within the bank's system. Customers interact with their accounts through a secure interface, like an ATM or online banking.

How does encapsulation improve security?

Encapsulation improves security by restricting access to the internal state of an object. This means that sensitive data can only be accessed or modified through well-defined methods, reducing the risk of unintended interference or misuse.

Are there any other benefits of encapsulation?

Yes, encapsulation also enhances code maintainability and flexibility. By hiding the internal workings, you can change the implementation without affecting other parts of the program that rely on the object's interface.
